If I may, Ill show you the difference between the portrayal of God in the OT vs the Quran.
Old Testament.
Read Numbers chapter 31.
The LORD said to Moses, “Take vengeance on the Midianites for the Israelites.After that, you will be gathered to your people.” So Moses said to the people, “Arm some of your men to go to war against the Midianites so that they may carry out the LORD’s vengeance on them.
Send into battle a thousand men from each of the tribes of Israel.”So twelve thousand men armed for battle, a thousand from each tribe, were supplied from the clans of Israel. Moses sent them into battle, a thousand from each tribe, along with Phinehas son of Eleazar, the priest, who took with him articles from the sanctuary and the trumpets for signaling.
They fought against Midian, as the LORD commanded Moses, and killed every man. Among their victims were Evi, Rekem, Zur, Hur and Reba—the five kings of Midian. They also killed Balaam son of Beor with the sword. The Israelites captured the Midianite women and children and took all the Midianite herds, flocks and goods as plunder. They burned all the towns where the Midianites had settled, as well as all their camps. They took all the plunder and spoils, including the people and animals, and brought the captives, spoils and plunder to Moses and Eleazar the priest and the Israelite assembly at their camp on the plains of Moab, by the Jordan across from Jericho.
Moses, Eleazar the priest and all the leaders of the community went to meet them outside the camp. Moses was angry with the officers of the army—the commanders of thousands and commanders of hundreds—who returned from the battle. “Have you allowed all the women to live?” he asked them. “They were the ones who followed Balaam’s advice and enticed the Israelites to be unfaithful to the LORD in the Peor incident, so that a plague struck the LORD’s people. Now kill all the boys. And kill every woman who has slept with a man, but save for yourselves every girl who has never slept with a man.
Vengeance. Plunder. Total annihilation. Murder of all married women and non virgins, save the virgins only. All the boys should be killed. Wonder why the virgins are saved!
Quran.
War is only allowed if you are not the aggressor. You are supposed fight for those who are oppressed. Or those who break a treaty etc. You have to have just cause. Even then when your enemy ceases their oppression, you are to stop and be merciful. You are allowed to fight only until there is no more persecution.
And fight in the cause of God against those who fight you, but do not aggress, God does not love the aggressors. And kill them wherever you encounter them, and expel them from where they expelled you, and know that persecution is worse than being killed. And do not fight them at the Restricted Temple unless they fight you in it; if they fight you then kill them, thus is the recompense of the rejecters. And if they cease, then God is Forgiving, Merciful. And fight them so there is no more persecution, and so that the system is for God. If they cease, then there will be no aggression except against the wicked. -Quran 2:190-193
You can see that the Quran does not tell you to be the victim but it establishes that you must not be the aggressor. You are allowed to fight back if someone aggressively fights with you. But even then, you are asked to forgive and cease fighting if the enemy seizes his fight. You are allowed to fight only until the persecution stops.
You must fight if someone is weak, being persecuted and are oppressed.
And why do you not fight in the cause of God, when the weak among the men and women and children say: “Our Lord, bring us out of this town whose people are wicked, and grant us from yourself a Supporter, and grant us from yourself a Victor!” - Quran 4:75
